DETAILED DESCRIPTION OF THE INVENTION

[0008] The present invention relates to a cleaning wipe, especially fordishware, flatware, pots and pans which comprises approximately:

[0009] (a) 20 wt. % to 95 wt. % of a water insoluble substrate; and

[0010] (b) 5 wt. % to 80 wt. % of a liquid cleaning composition beingcoated onto and/or impregnated into said water insoluble substrate,wherein said liquid cleaning composition comprises:

[0011] (i) 5 wt. % to 50 wt. %, more preferably 10 wt. % to 40 wt. % ofat least one anionic surfactant selected from the group of sulfateanionic surfactants and sulfonated anionic surfactants and mixturesthereof;

[0012] (ii) 0.1% to 30% of a surfactant selected from the groupconsisting of amine oxides, alkyl polyglucosides, zwitterionicsurfactants, ethoxylated nonionic surfactants and alkanol amides andmixtures thereof; and

[0013] (iii) the balance being water, wherein the water is less than 65wt. % of the composition and the composition has a pH of 6 to 8 and doesnot contain ammonium hydroxide, an alkali metal hydroxide, potassiumsorbate, a polysaccharide polymer, a polycarboxylate polymer, polyvinylalcohol polymer, polyethylene glycols, polyvinylpyrrolidone polymer ormethylvinylether polymer.

[0014] The wipe is not moist and does not feel wet, when touched by theuser. The wipe is activated, when placed in contact with water.

[0015] Suitable water-soluble non-soap, anionic surfactants used in theinstant compositions include those surface-active or detergent compoundswhich contain an organic hydrophobic group containing generally 8 to 26carbon atoms and preferably 10 to 18 carbon atoms in their molecularstructure and at least one water-solubilizing group selected from thegroup of sulfonate, sulfate and carboxylate so as to form awater-soluble detergent. Usually, the hydrophobic group will include orcomprise a C₈-C₂₂ alkyl, alkyl or acyl group. Such surfactants areemployed in the form of water-soluble salts and the salt-forming cationusually is selected from the group consisting of sodium, potassium,ammonium, magnesium and mono-, di- or tri-C₂-C₃ alkanolammonium, withthe sodium, magnesium and ammonium cations again being preferred.

[0016] Examples of suitable sulfonated anionic surfactants are the wellknown higher alkyl mononuclear aromatic sulfonates such as the higheralkyl benzene sulfonates containing from 10 to 16 carbon atoms in thehigher alkyl group in a straight or branched chain, C₈-C₁₅ alkyl toluenesulfonates and C₈-C₁₅ alkyl phenol sulfonates.

[0017] A preferred sulfonate is a mixture of an alkali metal ammoniumsalt and an alkaline earth metal salt of a linear alkyl benzenesulfonate having a high content of 3-(or higher) phenyl isomers and acorrespondingly low content (well below 50%) of 2-(or lower) phenylisomers, that is, wherein the benzene ring is preferably attached inlarge part at the 3 or higher (for example, 4, 5, 6 or 7) position ofthe alkyl group and the content of the isomers in which the benzene ringis attached in the 2 or 1 position is correspondingly low.

[0018] Other suitable anionic surfactants are the olefin sulfonates,including long-chain alkene sulfonates, long-chain hydroxyalkanesulfonates or mixtures of alkene sulfonates and hydroxyalkanesulfonates. These olefin sulfonate detergents may be prepared in a knownmanner by the reaction of sulfur trioxide (SO₃) with long-chain olefinscontaining 8 to 25, preferably 12 to 21 carbon atoms and having theformula RCH═CHR₁ where R is a higher alkyl group of 6 to 23 carbons andR₁ is an alkyl group of 1 to 17 carbons or hydrogen to form a mixture ofsultones and alkene sulfonic acids which is then treated to convert thesultones to sulfonates. Preferred olefin sulfonates contain from 14 to16 carbon atoms in the R alkyl group and are obtained by sulfonating anα-olefin.

[0019] Other examples of suitable anionic sulfonate surfactants are theparaffin sulfonates containing 10 to 20, preferably 13 to 17, carbonatoms. Primary paraffin sulfonates are made by reacting long-chain alphaolefins and bisulfites and paraffin sulfonates having the sulfonategroup distributed along the paraffin chain are shown in U.S. Pat. Nos.2,503,280; 2,507,088; 3,260,744; 3,372,188; and German Patent 735,096.

[0020] Examples of satisfactory anionic sulfate surfactants are thealkali metal or ammonium salt C₈-C₁₈ alkyl sulfate salts the ethoxylatedC₈-C₁₈ alkyl ether sulfate salts having the formula R(OC₂H₄)_(n) OSO₃Mwherein n is 1 to 12, preferably 1 to 5, and M is a metal cationselected from the group consisting of sodium, potassium, ammonium,magnesium and mono-, di- and triethanol ammonium ions. The alkylsulfates may be obtained by sulfating the alcohols obtained by reducingglycerides of coconut oil or tallow or mixtures thereof and neutralizingthe resultant product.

[0021] On the other hand, the ethoxylated alkyl ether sulfates areobtained by sulfating the condensation product of ethylene oxide with aC₈-C₁₈ alkanol and neutralizing the resultant product. The alkylsulfates may be obtained by sulfating the alcohols obtained by reducingglycerides of coconut oil or tallow or mixtures thereof and neutralizingthe resultant product. The ethoxylated alkyl ether sulfates differ fromone another in the number of moles of ethylene oxide reacted with onemole of alkanol. Preferred alkyl sulfates and preferred ethoxylatedalkyl ether sulfates contain 10 to 16 carbon atoms in the alkyl group.

[0022] The ethoxylated C₈-C₁₂ alkylphenyl ether sulfates containing from2 to 6 moles of ethylene oxide in the molecule also are suitable for usein the inventive compositions. These surfactants can be prepared byreacting an alkyl phenol with 2 to 6 moles of ethylene oxide andsulfating and neutralizing the resultant ethoxylated alkylphenol.

[0023] Other suitable anionic surfactants are the C₉-C₁₅ alkyl etherpolyethenoxyl carboxylates having the structural formula R(OC₂H₄)_(n)OXCOOH wherein n is a number from 4 to 12, preferably 5 to 10 and X isselected from the group consisting of

[0024] wherein R₁ is a C₁-C₃ alkylene group. Preferred compounds includeC₉-C₁₁ alkyl ether polyethenoxy (7-9) C(O) CH₂CH₂COOH, C₁₃-C₁₅ alkylether polyethenoxy (7-9)

[0025]  and C₁₀-C₁₂ alkyl ether polyethenoxy (5-7) CH2COOH. Thesecompounds may be prepared by condensing ethylene oxide with appropriatealkanol and reacting this reaction product with chloracetic acid to makethe ether carboxylic acids as shown in U.S. Pat. No. 3,741,911 or withsuccinic anhydride or phthalic anhydride. Obviously, these anionicsurfactants will be present either in acid form or salt form dependingupon the pH of the final composition, with salt forming cation being thesame as for the other anionic surfactants.

[0026] The instant composition can optionally include 0.1 wt. % to 15wt. % of a water-soluble zwitterionic surfactant, which can also be usedprovides good foaming properties and mildness to the present nonionicbased liquid detergent. The zwitterionic surfactant is a water solublebetaine having the general formula:

[0027] wherein R₁ is an alkyl group having 10 to 20 carbon atoms,preferably 12 to 16 carbon atoms, or the amido radical:

[0028]  wherein R is an alkyl group having 9 to 19 carbon atoms and a isthe integer 1 to 4; R₂ and R₃ are each alkyl groups having 1 to 3carbons and preferably 1 carbon; R₄ is an alkylene or hydroxyalkylenegroup having from 1 to 4 carbon atoms and, optionally, one hydroxylgroup. Typical alkyldimethyl betaines include decyl dimethyl betaine or2-(N-decyl-N, N-dimethyl-ammonia) acetate, coco dimethyl betaine or2-(N-coco N, N-dimethylammonio) acetate, myristyl dimethyl betaine,palmityl dimethyl betaine, lauryl dimethyl betaine, cetyl dimethylbetaine, stearyl dimethyl betaine, etc. The amidobetaines similarlyinclude cocoamidoethylbetaine, cocoamidopropyl betaine and the like. Apreferred betaine is coco (C₈-C₁₈) amidopropyl dimethyl betaine.

[0029] The instant composition can include an amine oxide semi-polarnonionic surfactants comprise compounds and mixtures of compounds havingthe formula:

[0030] wherein R₁ is an alkyl, 2-hydroxyalkyl, 3-hydroxyalkyl, or3-alkoxy-2-hydroxypropyl radical in which the alkyl and alkoxy,respectively, contain from 8 to 18 carbon atoms, R₂ and R₃ are eachmethyl, ethyl, propyl, isopropyl, 2-hydroxyethyl, 2-hydroxypropyl, or3-hydroxypropyl, and n is from 0 to 10. Particularly preferred are amineoxides of the formula:

[0031]  wherein R₁ is a C₁₂₋₁₆ alkyl and R₂ and R₃ are methyl or ethyl.The above ethylene oxide condensates, amides, and amine oxides are morefully described in U.S. Pat. No. 4,316,824 which is hereby incorporatedherein by reference.

[0032] The instant composition can include a C₁₂₋₁₄ alkyl monoalkanolamide such as lauryl monoalkanol amide or a C₁₂₋₁₄ alkyl dialkanol amidesuch as lauryl diethanol amide or coco diethanol amide.

[0033] The water soluble nonionic surfactants utilized in this inventionare commercially well known and include the primary aliphatic alcoholethoxylates, secondary aliphatic alcohol ethoxylates, alkylphenolethoxylates and ethylene-oxide-propylene oxide condensates on primaryalkanols, such a Plurafacs (BASF) and condensates of ethylene oxide withsorbitan fatty acid esters such as the Tweens (ICI). The nonionicsynthetic organic detergents generally are the condensation products ofan organic aliphatic or alkyl aromatic hydrophobic compound andhydrophilic ethylene oxide groups. Practically any hydrophobic compoundhaving a carboxy, hydroxy, amido, or amino group with a free hydrogenattached to the nitrogen can be condensed with ethylene oxide or withthe polyhydration product thereof, polyethylene glycol, to form awater-soluble nonionic detergent. Further, the length of thepolyethenoxy chain can be adjusted to achieve the desired balancebetween the hydrophobic and hydrophilic elements.

[0034] The nonionic detergent class includes the condensation productsof a higher alcohol (e.g., an alkanol containing about 8 to 18 carbonatoms in a straight or branched chain configuration) condensed withabout 5 to 30 moles of ethylene oxide, for example, lauryl or myristylalcohol condensed with about 16 moles of ethylene oxide (EO), tridecanolcondensed with about 6 to moles of EO, myristyl alcohol condensed withabout 10 moles of EO per mole of myristyl alcohol, the condensationproduct of EO with a cut of coconut fatty alcohol containing a mixtureof fatty alcohols with alkyl chains varying from 10 to about 14 carbonatoms in length and wherein the condensate contains either about 6 molesof EO per mole of total alcohol or about 9 moles of EO per mole ofalcohol and tallow alcohol ethoxylates containing 6 EO to 11 EO per moleof alcohol.

[0035] A preferred group of the foregoing nonionic surfactants are theNeodol ethoxylates (Shell Co.), which are higher aliphatic, primaryalcohol containing about 9-15 carbon atoms, such as C₁₁ alkanolcondensed with 9 moles of ethylene oxide (Neodol 1-9), C₁₂₋₁₃ alkanolcondensed with 6.5 moles ethylene oxide (Neodol 23-6.5), C₁₂₋₁₅ alkanolcondensed with 7 or 3 moles ethylene oxide (Neodol 25-7 or Neodol 25-3),C₁₄₋₁₅ alkanol condensed with 13 moles ethylene oxide (Neodol 45-13),and the like. Such ethoxamers have an HLB (hydrophobic lipophilicbalance) value of about 8 to 15 and give good O/W emulsification,whereas ethoxamers with HLB values below 8 contain less than 5ethyleneoxide groups and tend to be poor emulsifiers and poordetergents.

[0036] Additional satisfactory water soluble alcohol ethylene oxidecondensates are the condensation products of a secondary aliphaticalcohol containing 8 to 18 carbon atoms in a straight or branched chainconfiguration condensed with 5 to 30 moles of ethylene oxide. Examplesof commercially available nonionic detergents of the foregoing type areC₁₁-C₁₅ secondary alkanol condensed with either 9 EO (Tergitol 15-S-9)or 12 EO (Tergitol 15-S-12) marketed by Union Carbide.

[0037] Other suitable nonionic detergents include the polyethylene oxidecondensates of one mole of alkyl phenol containing from about 8 to 18carbon atoms in a straight- or branched chain alkyl group with about 5to 30 moles of ethylene oxide. Specific examples of alkyl phenolethoxylates include nonyl condensed with about 9.5 moles of EO per moleof nonyl phenol, dinonyl phenol condensed with about 12 moles of EO permole of phenol, dinonyl phenol condensed with about 15 moles of EO permole of phenol and di-isoctylphenol condensed with about 15 moles of EOper mole of phenol. Commercially available nonionic surfactants of thistype include Igepal CO-630 (nonyl phenol ethoxylate) marketed by GAFCorporation.

[0038] Also among the satisfactory nonionic detergents are thewater-soluble condensation products of a C₈-C₂₀ alkanol with a hetericmixture of ethylene oxide and propylene oxide wherein the weight ratioof ethylene oxide to propylene oxide is from 2.5:1 to 4:1, preferably2.8:1 to 3.3:1, with the total of the ethylene oxide and propylene oxide(including the terminal ethanol or propanol group) being from 60-85%,preferably 70-80%, by weight. Such detergents are commercially availablefrom BASF-Wyandotte and a particularly preferred detergent is a C₁₀-C₁₆alkanol condensate with ethylene oxide and propylene oxide, the weightratio of ethylene oxide to propylene oxide being 3:1 and the totalalkoxy content being about 75% by weight.

[0039] Condensates of 2 to 30 moles of ethylene oxide with sorbitanmono- and tri-C₁₀-C₂₀ alkanoic acid esters having a HLB of 8 to 15 alsomay be employed as the nonionic detergent ingredient in the describedcomposition. These surfactants are well known and are available fromImperial Chemical Industries under the Tween trade name. Suitablesurfactants include polyoxyethylene (4) sorbitan monolaurate,polyoxyethylene (4) sorbitan monostearate, polyoxyethylene (20) sorbitantrioleate and polyoxyethylene (20) sorbitan tristearate.

[0040] Other suitable water-soluble nonionic detergents which are lesspreferred are marketed under the trade name “Pluronics.” The compoundsare formed by condensing ethylene oxide with a hydrophobic base formedby the condensation of propylene oxide with propylene glycol. Themolecular weight of the hydrophobic portion of the molecule is of theorder of 950 to 4000 and preferably 200 to 2,500. The addition ofpolyoxyethylene radicals to the hydrophobic portion tends to increasethe solubility of the molecule as a whole so as to make the surfactantwater-soluble. The molecular weight of the block polymers varies from1,000 to 15,000 and the polyethylene oxide content may comprise 20% to80% by weight. Preferably, these surfactants will be in liquid form andsatisfactory surfactants are available as grades L 62 and L 64.

[0041] The alkyl polysaccharides surfactants, which can be used at ahydrophobic group containing from about 8 to about 20 carbon atoms,preferably from about 10 to about 16 carbon atoms, most preferably fromabout 12 to about 14 carbon atoms, and polysaccharide hydrophilic groupcontaining from about 1.5 to about 10, preferably from about 1.5 toabout 4, most preferably from about 1.6 to about 2.7 saccharide units(e.g., galactoside, glucoside, fructoside, glucosyl, fructosyl; and/orgalactosyl units). Mixtures of saccharide moieties may be used in thealkyl polysaccharide surfactants. The number x indicates the number ofsaccharide units in a particular alkyl polysaccharide surfactant. For aparticular alkyl polysaccharide molecule x can only assume integralvalues. In any physical sample of alkyl polysaccharide surfactants therewill be in general molecules having different x values. The physicalsample can be characterized by the average value of x and this averagevalue can assume non-integral values. In this specification the valuesof x are to be understood to be average values. The hydrophobic group(R) can be attached at the 2-, 3-, or 4-positions rather than at the1-position, (thus giving e.g. a glucosyl or galactosyl as opposed to aglucoside or galactoside). However, attachment through the 1-position,i.e., glucosides, galactoside, fructosides, etc., is preferred. In thepreferred product the additional saccharide units are predominatelyattached to the previous saccharide unit's 2-position. Attachmentthrough the 3-, 4-, and 6-positions can also occur. Optionally and lessdesirably there can be a polyalkoxide chain joining the hydrophobicmoiety (R) and the polysaccharide chain. The preferred alkoxide moietyis ethoxide.

[0042] Typical hydrophobic groups include alkyl groups, either saturatedor unsaturated, branched or unbranched containing from about 8 to about20, preferably from about 10 to about 18 carbon atoms. Preferably, thealkyl group is a straight chain saturated alkyl group. The alkyl groupcan contain up to 3 hydroxy groups and/or the polyalkoxide chain cancontain up to about 30, preferably less than about 10, alkoxidemoieties.

[0043] Suitable alkyl polysaccharides are decyl, dodecyl, tetradecyl,pentadecyl, hexadecyl, and octadecyl, di-, tri-, tetra-, penta-, andhexaglucosides, galactosides, lactosides, fructosides, fructosyls,lactosyls, glucosyls and/or galactosyls and mixtures thereof.

[0044] The alkyl monosaccharides are relatively less soluble in waterthan the higher alkyl polysaccharides. When used in admixture with alkylpolysaccharides, the alkyl monosaccharides are solubilized to someextent. The use of alkyl monosaccharides in admixture with alkylpolysaccharides is a preferred mode of carrying out the invention.Suitable mixtures include coconut alkyl, di-, tri-, tetra-, andpentaglucosides and tallow alkyl tetra-, penta-, and hexaglucosides.

[0045] The preferred alkyl polysaccharides are alkyl polyglucosideshaving the formula

R₂O(C_(n)H_(2n)O)r(Z)_(x)

[0046] wherein Z is derived from glucose, R is a hydrophobic groupselected from the group consisting of alkyl, alkylphenyl,hydroxyalkylphenyl, and mixtures thereof in which said alkyl groupscontain from about 10 to about 18, preferably from about 12 to about 14carbon atoms; n is 2 or 3 preferably 2, r is from 0 to 10, preferable 0;and x is from 1.5 to 8, preferably from 1.5 to 4, most preferably from1.6 to 2.7. To prepare these compounds a long chain alcohol (R₂OH) canbe reacted with glucose, in the presence of an acid catalyst to form thedesired glucoside. Alternatively the alkyl polyglucosides can beprepared by a two step procedure in which a short chain alcohol (R₁OH)can be reacted with glucose, in the presence of an acid catalyst to formthe desired glucoside. Alternatively the alkyl polyglucosides can beprepared by a two step procedure in which a short chain alcohol (C₁₋₆)is reacted with glucose or a polyglucoside (x=2 to 4) to yield a shortchain alkyl glucoside (x=1 to 4) which can in turn be reacted with alonger chain alcohol (R₂OH) to displace the short chain alcohol andobtain the desired alkyl polyglucoside. If this two step procedure isused, the short chain alkylglucosde content of the final alkylpolyglucoside material should be less than 50%, preferably less than10%, more preferably less than about 5%, most preferably 0% of the alkylpolyglucoside.

[0047] The amount of unreacted alcohol (the free fatty alcohol content)in the desired alkyl polysaccharide surfactant is preferably less thanabout 2%, more preferably less than about 0.5% by weight of the total ofthe alkyl polysaccharide. For some uses it is desirable to have thealkyl monosaccharide content less than about 10%.

[0048] The used herein, “alkyl polysaccharide surfactant” is intended torepresent both the preferred glucose and galactose derived surfactantsand the less preferred alkyl polysaccharide surfactants. Throughout thisspecification, “alkyl polyglucoside” is used to include alkylpolyglycosides because the stereochemistry of the saccharide moiety ischanged during the preparation reaction.

[0049] An especially preferred APG glycoside surfactant is APG 625glycoside manufactured by the Henkel Corporation of Ambler, Pa. APG25 isa nonionic alkyl polyglycoside characterized by the formula:

C_(n)H_(2n+1)O(C₆H₁₀O₅)_(x)H

[0050] wherein n=10 (2%); n=122 (65%); n=14 (21-28%); n=16 (4-8%) andn=18 (0.5%) and x (degree of polymerization)=1.6. APG 625 has: a pH of 6to 10 (10% of APG 625 in distilled water); a specific gravity at 25° C.of 1.1 g/ml; a density at 25° C. of 9.1 lbs/gallon; a calculated HLB of12.1 and a Brookfield viscosity at 35C., 21 spindle, 5-10 RPM of 3,000to 7,000 cps.

[0051] The water is present in the composition at a concentration of 5wt. % to 65 wt. %.

[0052] Preservatives which can be used in the instant compositions at aconcentration of 0.005 wt. % to 3 wt. %, more preferably 0.01 wt. % to2.5 wt. % are: benzalkonium chloride; benzethoniumchloride,5-bromo-5-nitro-1,3dioxane; 2-bromo-2-nitropropane-1,3-diol;alkyl trimethyl ammonium bromide; N-(hydroxymethyl)-N-(1,3-dihydroxymethyl-2,5-dioxo-4-imidaxolidinyl-N′-(hydroxy methyl) urea;1-3-dimethyol-5,5-dimethyl hydantoin; formaldehyde; iodopropynl butylcarbamata, butyl paraben; ethyl paraben; methyl paraben; propyl paraben,mixture of methyl isothiazolinone/methyl-chloroisothiazoline in a 1:3wt. ratio; mixture of phenoxythanol/butyl paraben/methylparaben/propylparaben; 2-phenoxyethanol;tris-hydroxyethyl-hexahydrotriazine; methylisothiazolinone;5-chloro-2-methyl-4-isothiazolin-3-one; 1,2-dibromo-2,4-dicyanobutane;1-(3-chloroalkyl)-3,5,7-triaza-azoniaadamantane chloride; and sodiumbenzoate.

[0053] The cleaning composition can contain 0.1 wt. % to 50 wt. % atleast one solubilizing agent selected from the group consisting of aC₂₋₅ mono, dihydroxy or polyhydroxy alkanols such as ethanol,isopropanol, glycerol ethylene glycol, diethylene glycol, propyleneglycol, and hexylene glycol and mixtures thereof, urea, and alkali metalcumene or xylene sulfonates such as sodium cumene sulfonate and sodiumxylene sulfonate.

[0054] The cleaning composition of this invention may, if desired, alsocontain other components either to provide additional effect or to makethe product more attractive to the consumer. The following are mentionedby way of example: Colors or dyes in amounts up to 0.5% by weight; pHadjusting agents, such as sulfuric acid or sodium hydroxide, can be usedas needed.

[0055] The composition can optionally contain 0.05 wt. % to 6 wt. % of aproton donating agent such as alpha hydroxy acid such as a compoundselected from the group consisting of lactic or citric acid, anantibacterial agent, hydrogen peroxide or an organic peroxide.Additionally, the composition can contain moisturizers, emollients,organic and/or inorganic builders, bleaching agents, a cellulosicpolymer such as methyl cellulose and hydroxy propyl methyl cellulose.

[0056] The product of the present invention comprises a water insoluablesubstrate with one or more layers. Each layer may have differenttextures and abrasiveness. Differing textures can result from the use ofdifferent combinations of materials or from the use of differentmanufacturing processes or a combination thereof. A dual texturesubstrate can be made to provide the advantage of a more abrasive sidefor cleaning difficult to remove soils. A softer side can be used forfine dishware and flatware. The substrate should not dissolve or breakapart in water. It is the vehicle for delivering the cleaningcomposition to dishware, flatware, pots and pans. Use of the substrateenhances lathering, cleaning and grease removal.

[0057] A wide variety of materials can be used as the substrate. Itshould have sufficient wet strength, abrasivity, loft and porosity.Examples include, non woven substrates, wovens substrates,hydroentangled substrates and sponges.

[0058] Examples of suitable non woven water insoluable substratesinclude, 100% cellulose Wadding Grade 1804 from Little RapidsCorporation, 100% polypropylene needlepunch material NB 701-2.8-W/R fromAmerican Non-wovens Corporation, a blend of cellulosic and syntheticfibres-Hydraspun 8579 from Ahlstrom Fibre Composites, and &0%Viscose/30% PES Code 9881 from PGI Nonwovens Polymer Corp.

[0059] Another useful substrate is manufactured by Jacob Holm-LidroRough. It is a composition material comprising a 65/35 viscoserayon/polyester hydroentangled spunlace layer with a hydroenlongatedbonded polyester scribbly layer.

[0060] Still another useful substrate is manufactured by Texel “TI”. Itis a composite material manufactured from a layer of coarse fiber 100%polypropylene needlepunch, an absorbent cellulose core and a fine fiberpolyester layer needlepunched together. The polypropylene layer canrange from 1.5 to 3.5 oz/sq. yd. The cellulose core is a creped paperlayer ranging from 0.5 to 2 oz./sq. yd. The fine fiber polyester layercan range from 0.5 to 2 oz./sq. yd.

[0061] Still another composite material manufactured by Texcel from alayer of coarse fiber 100% polypropylene needlepunch layer, an absorbentcellulose core and a fine fiber polyester layer needlepunched together.The polypropylene layer can range from 1.5 to 3.5 oz/sq. yd. Thecellulose core is a creped paper layer ranging from 0.5 to 2 oz/sq. yd.The fine fiber polyester layer can range from 0.5 to 2 oz/sq. yd. Thepolypropylene layer is flame treated to further increase the level ofabrasivity. The temperature of the flame and the length of time thematerial is exposed can be varied to create different levels of surfaceroughness.

[0062] The abrasiveness is tested by cutting one quarter inch thickLucite boards to fit an abrader bed. The boards are marked to indicatethe track of the wipes during abrasion (approximately 2¼ and 4½ inchesfrom one long edge) and three spots along the track (6, 9 and 12 inchesfrom the short end). This gives unique and reproducible locations atwhich to do gloss measurements which are in the center of the abrasiontrack.

[0063] Using a BYK-Gardener Haze-Gloss glossmeter, the indicated spotsare measured for starting gloss. An average and standard deviation isreported for each track using the three measurements.

[0064] Pieces of the wipes are cut approximately 3 inches by 2 inches.This piece is wrapped around a piece of sponge that fits in a holder forthe abrader. (Indication should be made of whether the material is beingused in the machine or cross direction). This wrapped sponge is placedin the holder, tucking all the edges of the wipe into the holder so thatit is kept firmly in place. The dry sponge is wetted with approximately20-25 g of water (either deionized, distilled or tap as the experimentdesires). This is done so that there are two wipes in the trial.

[0065] The gloss measured Lucite board is placed in the abrader bed. Setthe abrader for 500 cycles and start.

[0066] After the abrader cycles have ended, the Lucite board is removed.It is wiped dry with paper towel to remove any residual water. It isalso inspected for any fingerprints incurred during handling and theseare also wiped clean. Remeasure the gloss at the specified spots againand again report the average of these three spots and the standarddeviation for each track.

[0067] The higher the abrasiveness of the wipe, the more that itroughens the surface of the Lucite and the more the gloss is reduced.The most abrasive of the wipes therefore give the greatest decrease ingloss. Results for this test are given below.

[0070] A composite dual textured material manufactured by Kimberly Clarkcomprises a coarse meltblown polypropylene, polyethylene, or polyesterand high loft spunbond polyester. The two materials can be laminatedtogether using chemical adhesives or by coprocessing the two layers. Thecoarse meltblown layer can range from 1 to 3 ounces per square yardwhile the highloft spunbond layer can range from 1 to 3 ounces persquare yard.

[0071] Another example of a composite is a dual textured materialcomposed of coarse meltblown polypropylene, polyethylene, or polyesterand polyester/cellulose coform. The two materials can be laminatedtogether using chemical adhesives or by coprocessing the two layers. Thecoarse meltblown layer can range from 1 to 3 ounces per square yard. Thecoform layer can range in composition from 30% cellulose and 70%polyester to 70% cellulose and 30% polyester and the basis weight canrange from 1.5 to 4.5 ounces per square yard.

[0072] The product of the present invention comprising mutliple layersmay be ultrasonically bonded after applying the coating of one or moreof the layers. Alternatively layers may be bonded together byneedlepunch, thermal bonding, chemical bonding, or sonic bonding priorto applying the coating and/or impregnation.
